Sound-Absorbing CMU - Type IVRF

Trenwyth Acousta-Wal®

ACOUSTA-WAL® sound-absorbing masonry units are your acoustical and aesthetic solution in one product. Whether it's a school gym, lecture hall or performance arts center, ACOUSTA-WAL is your solution to sound absorption and control. Its unique design controls sound transmission as it absorbs sound waves. ACOUSTA-WAL absorbs sound at all frequencies ... even the difficult-to-control low frequencies.

ACOUSTA-WAL® is available in Trenwyth Astra-Glaze-SW+® and Trendstone® finishes, as well as natural gray. (Astra-Glaze-SW+® units are available with recycled content.)

Use Type IVRF Units for broad range sound absorption, such as school gymnasiums, lecture halls, and performing art centers.

Available in 8", 10" or 12" thicknesses, Type IVRF Units have wide funnel-shaped slots, opening into a two chamber cavity separated by a metal septum laminated to a fiberglass filler. Fiberglass fillers are chemically inert, vermin resistant, incombustible and moisture-proof. Type IVRF Units also offer the advantage of open cavities for vertical reinforcing conduits or pipes.
